后台接口程序
public Map<String, Object> getMyRolls(JSONObject head,JSONObject body) throws Exception {

         
     // 业务信息
     Map<String, Object> attributes=new HashMap<String, Object>();

1. offset=PagerUtil.getOffset(Integer.valueOf(page),Integer.valueOf(rows));

             List<Map> list=super.findListbySqlReturnMapByPage(queryString+whereString+orderString, offset, Integer.valueOf(rows));
                     
            attributes.put("coupons", list);
            
        }else{

2. new InterfaceException(new ErrorBean(ErrorCode.USER_NO_LOGIN));

        }
        
    }else{

1. new InterfaceException(new ErrorBean(ErrorCode.USER_NO_LOGIN));

     }
     

1. attributes;

   }

   输出怎么没有list查的数据？？
